^ Thats what I do for crooked toes, I don't use any cardboard though. Take a band aid and cut the absorbent pad out. Take one sticky side and place it on the bottom of the chicks foot. Straighten the toes as best as you can and then place the other sticky side on top. Seal the two pieces together, getting in between the toes to seal them in place. Trim the outside edges if necessary. Leave the shoe on for a few days, and when you take it off the toes should stay where you put it. I don't think a bent toe would hinder it much if you didn't fix it though (but I would)
